PATENT OFFICE CHARLES HILAIRE HENRI ROD-ANET, 0Fv VERSAILLES, FRANCE, ASSIGNOR TO SOCIT ANONYME: ETABLISSEMENTS ED., JAEGER, OF SEINE, FRANCE, A, JOINT-STOCK COMPANY 0F FRANCE WINDSCREEN ADJUSTING- MECHANISM Application filed Apri1.15, k1929, Serial No.` 355,297, and in France April 20, 1928.

The present invention reljates to mechanlsms allowing, from` the interior cfa motor rise from his seat.

The known mechanisms are usually applied to wind screens pivoted at their upper part on the front posts of the carriage body, so that their lower edge may be moved away at will from the awning arched member of the drivers place for providing an adjustable air inlet within the car. comprise rigid members which, even when is completely tilted in closed position, are very apparent andspoil the look of the car; they have, moreover, the inconvenience of constituting a rigid` connection between the wind screen and the'awning of the drivers place, this causing abnormal stresses on the various joints when the car-A ensured by a screw 3 and the suitable'relariage body becomes distorted.

For remedying invention has for object vthe new application to wind screen adjusting mechanisms, of resiliently distortable connections capable ot exerting both a pulling and a pushing action on the wind screen and of becoming distorted inorder to be withdrawn within a reduced space. /Vind screen adjusting mechanisms to whichare applied these resiliently distortable connections can be constructed in various ways. They can di'er from eachother particularly: v

(a) By the choice of the operating member and the nature of the displacements adopted for the latter. l c

(b) By the kinematic system chosen for connecting this operating member to the flexible connections acting on the wind screen.

(c) By the mode of construction of the flexible connections. f y In a form of construction of such a mecha'- nism which seems lto be the most advantageous, the operating member receives movements of rotation and is angularly connected to a drum on which is secured one of the ends of the exible connections acting on the wind screen to be controlled.

The accompanying drawings illustrate, by.

way of example, a form of construction o4 These mechanisms" these inconveniences, the

a wind screen adjusting mechanism utilizing the above arrangement.

Figures 5 and respectively according to lines A-A' and B-B of Fig. 4.

Figures 7 and 8 are respectively a front View and a side view of a device for attaching on the wind screen the resiliently dis- Vtortable member.

The operating mechanism comprises -aframe constituted by a casing made 1n two part-s 1 and 2 theV connection ot which 1s tive position of which are determined bythe engagement of claws, provided on one of the said parts, into perforations 4 (Fig. 6)

formed in the other part. Y

` The contact faces of the parts l and 2 are cut away so asV to present bearing portions for a spindle 5 immobilized in translationl by the engagement of a collar 6 ingrooves 6a. The spindle 5 passes through the inner cavity or chamber of the casing and carries a worm handle which, as in the example illustrated, can be yconstituted by a knob l2 having a milled periphery, pinned at k13 and owing to `which a movement of rotation in kone direction or the'other can be imparted to both pulleys'9 and l0. he extreme angular positions of the pulleys 9 and l0 can b e determined by abutments and, for instance by i Y bosses or claws 14 pressing againstvthe ends 6 are two sect-ions, made i y The spindle 5 rey ceives, externally to the casing, an operating the turns of which preferably touch each other, and having a cross section suited to the importance of' the stresses to be transmitted.

These tubes enter within the casing through perforations 18 provided in the front wall of the said casing and located in the planes of lthe peripheral grooves of each of the pulleys 9 and 10. The tubes 16 and 17 can be attached to the said pulleys by any suitable means and, for instance, and as illustrated, by the engagement in a radial perforation of eachpulley of the end heel piece of a bent rod 19 (F ig. 5) fitted into one of the tubes and soldered to the turns of the latter.

vThe casing is secured, by lugs 20 perforated for the passage of screws or bolts, within the part of the car reserved for the driver and, for instance, on the awning arched member, so that the driver may have easy access to the operating knob 12. rThe outer kends of the tubes 16 and 17 are secured to the lower edge of the wind screen. i

The connection of the tubes 16 and 17 to the wind screen can be effectedV by any'suitable means and, particularly, by means of.

the simple device illustrated in Figs. 7 and 8 and included in the scope of the invention.

Y The free ends of both tubes 16 and 17 are connected by a yoke constituted by a rod 21 the bent ends of which it in the tubes on a n certain width and are held therein by soldering or any'equivalent means. A fork-piece 22 embraces the middle portion of the rod 21 and is secured on the lower edge of the wind screen 23 by one or more screws 274. It will `be seen that according to the direction of the rotation imparted to the knob 12, the tubes exert a thrust or a pull on the wind screen V23 for opening or closing the latter. In the closed position, the tubes 16 and 17 are nearly completely withdrawn within the casing and the apparent members on the outer face ofthe wind screen are constituted by a branch, of reduced dimension, of the fork-piece 22.,

As indicated above, no rigid `connection is interposed between the wind screen Vand its operating mechanism, so that the distortions of the carriage can freely take place.

i What I claim as my invention and desire to secure by Letters Patent is 1. In a mechanism for operating the wind screens of motor vehicles, a flexible cable capable of transmitting pulling and pushing strains, means for securing one end of the said cable to the wind screen, a fixed frame, a drum adapted to rotate in the said fixed frame, means for securing the second end of a drum adapted to rotate in the said lixed frame, means'for securing the second end of the cable to the said drum and irreversible operating means for rotating the said drum.

3. In a mechanism for operating the wind screens of motor vehicles, a flexible.V cable capable of transmittingv pulling and pushing` strains, means for securing :one end of the said cable to the wind screen, a fixed frame, a drum adapted to rotate in the said fixed frame, means tor securing the second end of the cable to the said drum, a helicoidal toothed wheel, vmeans for securing the said wheel to the said drum, a screw engaging with the said wheel and means for rotating the saidvscrew at will.

4;. In a mechanism for operating the wind 'screens of motor vehicles, two flexible cables capable of transmitting pulling and pushing strains, means for simultaneously securing one end of each of the said cables to the wind screen, a fixed frame, a drum adapted to rotate in the said fixed frame, means for securing the second end of each of the said cables to the said drum, operating means for rotating the said drum acting to prevent accidental rotation of the said drum when not acted upon by the said operating means.

In testimony whereof I have signed this specification.
